“…Griffin et al (1999a, b) found that sabinene incremental aerosol reactivity is between 40% and 80% greater than that for apinene, and noted that sabinene was efficiently converted to aerosol via nitrate radical reactions, suggesting that nighttime chemistry may be important for aerosol formation in this region. Koch et al (2000) also found that sabinene (which has exocyclic double bonds) has a higher new particle formation rate in the presence of O 3 compared to other common monoterpenes. These aerosol yield characteristics of sabinene, combined with the trend of increasing area in H. brasiliensis plantations, could have very significant implications for secondary organic aerosol levels and possibly visibility in this region.…”

“…The relationship between yield and ozone level was similar to the relationship between mass concentration and ozone, although the yield for POC appeared to level off above ~60 ppb ozone, as shown in Figure 4b. Limonene, α-terpinene, and terpinolene have the highest SOA-forming potential of the terpenes in the tested products Koch et al, 2000). The total terpene level (in ppb) introduced was roughly constant from one experiment to the next, but the fraction of terpenes with high SOAforming potential decreased from 100% in OOD to 65% in POC to 10% in AFR.…”

We analyzed secondary organic aerosol (SOA) data from a series of small-chamber experiments in which terpene-rich vapors from household products were combined with ozone under conditions analogous to product use indoors. Reagents were introduced into a continuously ventilated 198 L chamber at steady rates. Consistently, at the time of ozone introduction, nucleation occurred exhibiting behavior similar to atmospheric events. The initial nucleation burst and growth was followed by a period in which approximately stable particle levels were established reflecting a balance between new particle formation, condensational growth, and removal by ventilation. Airborne particles were measured with a scanning mobility particle sizer (SMPS, 10 to 400 nm) in every experiment and with an optical particle counter (OPC, 0.1 to 2.0 µm) in a subset. Parameters for a three-mode lognormal fit to the size distribution at steady state were determined for each experiment. Increasing the supply ozone level increased the steadystate mass concentration and yield of SOA from each product tested. Decreasing the airexchange rate increased the yield. The steady-state fine-particle mass concentration (PM 1.1 ) ranged from 10 to > 300 µg m -3 and yields ranged from 5% to 37%. Steady-state nucleation rates and SOA mass formation rates were on the order of 10 cm -3 s -1 and 10 µg m -3 min -1 , respectively.

“…Therefore we decided to conduct our simulations assuming constant surface tensions. For pinic acid a surface tension has been estimated theoretically to 34.22 dyn cm −1 (Cai and Griffin, 2005) and to (110±90) dyn cm −1 (Koch et al, 2000) from experimental data. Since product 1 exhibits a much lower vapour pressure than pinic acid (as will be discussed below), we consider it reasonable to apply an accordingly adjusted value for σ 1 .…”

Abstract. Secondary organic aerosol (SOA) formation has been investigated as a function of temperature and humidity for the ozone-initiated reaction of the two monoterpenes α-pinene (243-313 K) and limonene (253-313 K) using the 84.5 m 3 aerosol chamber AIDA. This paper gives an overview of the measurements done and presents parameters specifically useful for aerosol yield calculations. The ozonolysis reaction, selected oxidation products and subsequent aerosol formation were followed using several analytical techniques for both gas and condensed phase characterisation. The effective densities of the SOA were determined by comparing mass and volume size distributions to (1.25±0.10) g cm −3 for α-pinene and (1.3±0.2) g cm −3 for limonene. The detailed aerosol dynamics code COSIMA-SOA proved to be essential for a comprehensive evaluation of the experimental results and for providing parameterisations directly applicable within atmospheric models. The COSIMA-assisted analysis succeeded to reproduce the observed time evolutions of SOA total mass, number and size distributions by adjusting the following properties of two oxidation product proxies: individual yield parameters (α i ), partitioning coefficients (K i ), vapour pressures (p i ) and effective accommodation coefficients (γ i ). For these properties temperature dependences were derived and parameterised. Vapour pressures and partitioning coefficients followed classical Clausius -Clapeyron temperature dependences. From this relationship enthalpies of vaporisation were derived for the two more and less volatile product proxies of α-pinene: (59±8) kJ mol −1 and (24±9) kJ mol −1 , and limonene: (55±14) kJ mol −1 and (25±12) kJ mol −1 . The more volatile proxy components had a notably low enthalpy Correspondence to: H. Saathoff (harald.saathoff@imk.fzk.de) of vaporisation while the less volatile proxy components gave enthalpies of vaporisation comparable with those of typical products from α-pinene oxidation, e.g. pinonaldehyde and pinonic acid.
